This has leaves resembling those of B. horneensis, but the flowers are fewer and 

 larger. Beccari's Sumatra specimens (P.S. 857), in fruit only, appear to belong to 

 this species. 



15. Begonia vENgsTA, King n. sp. Rhizome slender, creeping; whole 

 plant glabrous. Leaves reniformly ovate, shortly acuminate, the basal 

 sinus deep ; the edges sub-entire or remotely and minutely denticulate ; 

 both surfaces smooth, shining : main- nerves 7, radiating from the baso, 

 slender; length 3 to 5*5 in.; breadth 2 to 35 in.; petioles unequal, 

 slender, from 6 to 12 in. in length. Peduncles 3*5 to 6 in. long, bearing 

 about 3 pedunculate pinkish-white flowers near the apex. Male ; sepals 

 2, ovate-rotund, blunt, '75 in. long. Petals 2, somewhat larger. Stamens 

 narrowly oblong, with a large apiculus ; filaments unequal, the inner 

 ones long, the outer short. Females smaller than the male, the perianth 

 of 5 unequal broad blunt segments ; styles very short, with numerous 

 broad depressed lobules. Capsule *3 in. long and l']5 in. broad (to the 

 ends of tJie wings) ; lateral wings more than half as long as the posterior, 

 broadly triangular, blunt ; posterior wing oblong, blunt, -7 in. long.

The leaves are not unlike those of B. paupercula and B. borneensis but the flowers 

 are large and handsome. 



16. Begonia megapteroidea, King n. sp. Rhizome as thick as a 

 swan-quill, creeping on rocks. Leaves broadly and very obliquely ovate, 

 acuminate ; both sides of the base rounded but very unequal, the sinus 

 between them wide, the edges remotely and minutely dentate, upper 

 surface glabrous ; tlie lower also glabrous except the rusty-pubescent 

 nerves which are also scaly near the base : main- nerves about 8, radiat- 

 ing from the base, the larger branched and all rather prominent ; length 

 (from ap of petiole to apex of blade) 4 to 5 in. ; breadth 4 to 5 in. ; 

 petiole 12 to 16 in. long, glabrous. Peduncles from half as long to 

 nearly as long as the leaves, glabrous, ebracteate below the flowers, 

 Male flowers : sepals rotund-ovate, very obtuse, 1 in. long and '6 to 7 in. 

 broad ; petals much smaller, elliptic : stamens numerous, in a conical
